class V (5) laser build specifications

[lasermanXYZ]

(didnt know where to put this topic, there is no "lasers in science fiction" section)

to build the first class5 laser it must can do the following:

1) emit black light (maybe by inverting white light, iam not sure about that)
2) laser power output must be stable below 0 in negative range

any other must can's?

That is speculative. Class V isn't defined and could be anything.
Why not class VI with imaginary beams and dots.

please, stay focused with me. iam trying here to roughly define a class5 laser.

It should be not named a "laser", because "laser" means light amplificated by stimulated emission of radiation. Emitting "black light", that would mean "absence of light", or some device that would "absorb light", hence not a "Laser".

Darkon collectors, bro. Pear shaped. Suck all the darkons out of a room. They totally get rid of the dark. When they get full, you gotta throw 'em out and screw in another one.

Black lasers actually exist. When laser wave-fronts cancel in interference patterns they become invisible.

Not exactly though, but in a semi-fictional setting maybe.

Yeah I've heard of these. They can only collect darkons in a straight line. The darkons left behind object are left as what they call shadows/ darkon pools.

Wasn't there a class 5 planetary disrupter in some episodes of Deep Space 9? If I remember right it was class 5. Remember when Gul Dukat decided to become a freedom fighter and Kira was helping him and he had a ship that was too small and Kira came up with the idea of mounting the planetary disrupter in the cargo bay. I don't remember what season or episodes it was.

I suppose anything class 5 should be able to damage or destroy an orbiting spacecraft.

One thing bothers me about lasers and other energy weapons in science fiction. My experience with lasers has changed how I view science fiction. Ever notice how even when using weapons that can vaporize objects or cut through thick metal or walls etc. no one is ever wearing safety glasses? Also in space the beam is always visible, in reality it would rarely be visible unless you were in a nebula or some big gas cloud.

As laser classes are defined with respect to the safety precautions needed, maybe Class 5 should be a designation for a laser under control of an operator who should never have access to lasers.

Class V laser? Are you talking about the laser that's ungodly powerful that the objects that only touch the laser beam once gets obliterated?

Never mind the actual Class V laser in Germany (X-ray free electron laser), that only the professionals are allowed anywhere near the laser control panel. The faculty that houses this huge laser's tightly guarded for this reason as well - laser light of hard X-ray wavelength is extremely bright (about maybe several tens gigawatts) that nothing will survive except for ablative-absorption target.

Nothing in Physics limits the amount of energy that can be bound into a laser beam. Funnily enough a death star type laser is actually possible

True, to the point. It will be impossible to scale, due to thermal limits of lasing mediums as electron confinement is actually important to lasing physics.

Remove the electron bandgap, you have no light at all, and magnets can only take the place of electron shells. The only difference between atoms' electron shells and magnets is that there are a lot more room for wavelength tuning than with specific ingredients in lasing material.

So, simple answer is no. Unless you go with free electron laser - even government-sponsored laser may have to have their huge Neodymium laser crystals replaced frequently due to energy density they have to endure.
